Shunt Current Control Methods in Electrochemical Systems Applications

摘要

Electrochemical systems with a common electrolyte shared by a group of cells in series have shunt currents. A portion of the current supplied to an electrochemical cell is diverted through the common electrolyte pathways created by the manifold and channel electrolyte feed systems to the individual cells. These shunt currents produce the effects in the electrochemical cell system that are undesirable. Power is consumed, oxidation and reductions reactions occur in the production of the shunt currents, corrosion of the electrodes can take place and the products of an electrochemical reaction can be contaminated with products produced in the shunt current redox reactions. These and other factors have made the shunt current effects a problem in electrochemical systems. This paper discusses the experimental confirmation of theories and application of the shunt current control methods to functioning electrochemical systems. (ERA citation 08:015039)
